Low- and intermediate-pT di-hadron distributions in Au + Au collisions at 
GeV from STAR
M J Horner (for the STAR Collaboration)
Show affiliationsWe present a study of low- and intermediate-pT correlated azimuthal angular distributions in Au+Au collisions at 
from STAR. The near side associated yields in Au+Au collisions are found to be strongly enhanced, due to contributions from large Δη. The enhancement is reduced for high ptrigT. We show a strong broadening and enhancement of the away-side yield. The evolution of the away-side shape may be explained as the sum of a broad structure from bulk response and a narrow peak from jet fragmentation.
